FIG. 1 illustrates a perspective view of the pipelayer showing my new design, wherein a longitudinal axis of the main assembly is perpendicular to a longitudinal axis of the undercarriage.

FIG. 2 illustrates another perspective view of the pipelayer, wherein the longitudinal axis of the main assembly is parallel to a longitudinal axis of the undercarriage.

FIG. 3 illustrates another perspective view of the pipelayer, wherein the longitudinal axis of the main assembly is parallel to a longitudinal axis of the undercarriage.

FIG. 4 illustrates an orthogonal view of the pipelayer, wherein the longitudinal axis of the main assembly is perpendicular to a longitudinal axis of the undercarriage; and,

FIG. 5 illustrates another orthogonal view of the pipelayer, wherein the longitudinal axis of the main assembly is parallel to a longitudinal axis of the undercarriage. 

The ornamental design for a pipelayer, as shown and described.
